Two Spotted Spider Mite

Summary A three-season field evaluation showed that eggplants (Solanum melongena) are very tolerant to damage caused by the two-spotted spider mite, Tetranychus urticae. Although large numbers of the predacious mites, Neoseiulus fallacis or Phytoseiulus persimilis were released, biological control of the two-spotted spider mite could not be sustained in the field. Based on a preliminary comparison of yield in both sprayed and unsprayed plots and on a three-year qualitative assessment, a tentative action threshold of 600 two-spotted spider mites per leaf would not decrease yield and would reduce the number of acaricide treatments per season. The new acaricide spirodiclofen was effective against the two-spotted spider mite in a preliminary trial.

Three predators Scolothrips sexmaculatus Pergande, Phytoseiulus persimilis Athias - Henriot and Stethorus punctillum Weise were used to control two-spotted spider mite, Tetranychus urticae Koch on potted bean plants. Mite population increased exponentially on the untreated plants, but on the predator treated plants, increase of mite population was checked and remained within minimum number. Early release of predator checked the mite population earlier and kept it lower than on late released plants. All the three predators may be used as bio-control agents against two-spotted spider mite. Key words: Control, Tetranychus urticae, Scolothrips sexmaculatus, Phytoseiulus persimilis, Stethorus punctillum and bio-control agents.   doi:10.3329/ujzru.v27i0.1954 Univ. j. zool. Rajshahi Univ.
